APPARATUS FOR TRIMMING SlDES OF ROADS.

SPECIFICATION forming part of Letters Patent No. 653,510, dated July 10, 1900.

Application filed December 8, 1899. Serial No. 739,630. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER HOGG, county road surveyor for the county'of Elgin, a subject of the Queen of the United Kingdom of GreatBrit-ain and Ireland, and a resident of 24 Academy street, Elgin, Scotland, have invented an Improved Apparatus for Trimming the Sides of Roads, of which the following is a specification.

This invention relates to an improved apparatus for trimming and dressing the edges of roads, adapted to be worked by engines known as traction-engines or steam-rollers, whereby the said road edges can be pared and dressed expeditiously by one operation, thereby securing superiority of work and a saving of labor and expenditure.

The construction and yoking of this apparatus are illustrated 'in the accompanying drawings, in whioh- Figure 1 is an'elevation, and Fig. 2 a plan, of the apparatus, showing as much of the comotive or engine as illustrates the attachment less parts hereinafter described. Fig. 3 is an elevation, and Fig. 4 a horizontal sec- 1 tion, on the line X Y, to an enlarged scale, of

the shear n, Figs. 1 and 2. Figs. 5 and 6 are similar viewsof the shear m, Figs. 1 and 2.

Referring to the said drawings, the appa ratus consists of an iron frame a, carried at the rear bytwo wheels 0 c, which run on the road, the wheel 0 being less in diameter than the wheel 0 in order to allow for the contour or camber of the road edge. The said wheels are carried on the axle 0 the wheel 0 being keyed to the axle outside the frame a, while the wheel 0 runs loosely on the axle inside the frame. The axle is held in bush-blocks,which are adjustable as regards height by a regulating key-pin 0 The apparatus is yoked or attached to the engine as follows: To the rear portion of the engine (marked B on the drawings) are two angle-lugs b riveted or otherwise permanently attached to the side b of the tender at rear of road-wheel of engine opposite the top of the frame a and having a hole for pin and cotter. Two similar lugs are riveted to the front of fire-box at front of road-wheel. (Not shown on the drawings.) Between the lugs 19 is fixed by'pin and cotter an iron bar N, which passes around the outside of road-'wlieel and is similarly secured between the lugs formerly mentioned as being fixed in front of road-wheel. From the front outside angle of the bar 11 is riveted another lug, between which and the front of the engine is a strong tension-rod fixed just under the smoke-box fit the journal of the boss and held in'posi- Onto the tion by a cap fixed to end of boss. front of b is securely riveted at top and'bottorn a strong bar 6 leaving sufficient space between it and the foregoing to allow connection of the apparatus and give ample play both lateral and vertical. The apparatus is attached to the bar I) by two iron plates se-' curely fixed to the frame a, 5 being arranged between them. The attachment is secured by the insertion of a friction-roller, pin, and cotter 19 in front. This completes the connection necessary to transmit the traction of the engine to the apparatus.

The apparatus is held in a relative position to the engine by a triangular iron brace-bar cl, fixed with a stout hinged connection to the frame a and to the ordinary coupling 6 at rear of engine.

The apparatus is raised or lowered by ale= ver e, the fulcrum of which is fixed into the iron barf, which is riveted to the bar 17 and shaped as shown in Fig. 1. It is further se cured by a screw-stud to the top of the ringbush 19 The notched regulating-quadrant g is also fixed to the bar f. The attachment between the point of the lever e and front part of the frame a is effected by a connection into whichisintroduced aspring h, Figs. 1 and 2, which'allows the apparatus to rise over any dangerous obstructions. This completes the whole connection between engine and apparatus for traction, holding in posi' tion, for carrying, raising or lowering, and generally regulating the apparatus. It will be observed that the main road-wheel of engine is thereby, in efiect, adapted as leading wheel of the apparatus and that by compress-2 ing the'springlz by the lever'e so much of the weight of the engine as may in certain cases be necessary for the working of the apparatus is (in addition to the weight of the apparatus itself) transmitted by this means to the cutting-tools.

The cutting-tools are herein described separately. The apparatus pares the edge of roads by the paring-wheel 7c, the whole circumference of which is sharpened. It is of circular form, and the blade is fitted to an iron boss by countersunk bolts or the like, on which duplicates can be quickly and easily fixed. A stout axle-spindle is screwed into the boss. The cutting-wheel is held in position on the frame by a U-shaped shank made of iron of a square or other shape in section, a portion of the thickness of which is let into the frame a. It is regulated and secured to the frame by two tightening-shackles 7c. The inner end of the axle is similarly secured to the part a of frame. The axle revolves in a tube-bush 70 which is renewable, the whole being strong and rigid to withstand shock or pressure. The wheel is set to pare the edge with a slight slope toward the road, as shown more particularly in Fig. 2, and is used, along with the shear m and point m (hereinafter described,) when the apparatus is trimming a side with an upright border, but, together with the said point, is removed when the proj ectin g-point shear m hereinafter described, is in use trimming a side opposite a ditch.

Immediately behind the paring-wheel k is the cutting-shear m mounted on a strong iron or steel stock m, which stock is securely fixed to the frame ct with screw-bolts, as shown on Fig. 1, and with an adjustable screw-bolt inserted through the web m and the crossbar a Fig. 1. The cutting portion of the shear is set to its work at an angle of about thirty degrees and is fixed in a checked bearing to the lower edge of the upper plate to admit of renewals. The pointm of the shear m, used along with the paring-wheel 70 at an upright border, being subject to considerable tear and wear is made of hard-chilled castiron. It is held in position by a socket at the lower front part of the stock m and secured by a bolt.

The projecting-point shear m used for trimming sides opposite ditches, has an upper plate m on which the cutting part m is fixed on a checked bearing for renewals. It is fixed as an extension (forward) of the shear m by first removing the wheel 7.: from its bush and the point m from its socket and is attached to the front end of the shear m by bolts. This projecting shear is stayed in front by two tie-rods m joined together near the shear, at the back of which they are bolted, the other ends being secured one to the nearest point of the frame a, the other to the nearest point of the frame (1 A little to the front of the shear m and nearer to the locomotive is another cuttingshear 01, mounted on a stock a similar to that of the shear m and bolted to the under side of the portion a of the frame. The upper plate of this shear is shorter than m. The cutting part of the shear is bolted to the lower edge of the front plate and projected in a tusk somewhat flattened at the heel end in order to allow it to pass under loosened materials removed by the front part. This shear is stiffened and regulated transversely by a shank of, which is inserted into a socket in the stock 11. and passed up through a slot in the plate at. The point a is exactly the same in quality and shape and is fixed in the same manner as that described for the shear m. The said shears m and n are shown to a larger scale and removed from the apparatus in Figs. 3 to 6.

Toward the rear of the apparatus is the raking-shear 0. This shear has a deeper upper plate than the other two. As shown on Fig. 1, the cutting part 0 is bolted to a checked bearing on the lower edge of the upper plate for convenient renewals. At the rear end this cutter is extended as a projecting tusk O flattened at the heel to facilitate its passage underneath materials loosened in front. This shear is drawn along by two drag-bars p and p, diagonally braced, hooked on with hinged joints to the cross-bar a In addition to regulation as to depth of cut by the raising or lowering of the apparatus by the lever c this shear is separately regulated as to pressure and depth of cut by the lever 19 through the connecting-rod p and cranks p, fixed on the axle p and acting on a springp, attached to and seated on a bracket fixed on the dragbar p at the back of the shear 0.

The shield r is fixed to the frame a for the purpose of preventing the escape of material loosened by the shears m and it beyond the range of the raking-shear 0.

The working is performed after construction and attachment of the apparatus as follows: The apparatus being transported to the road edge to be operated on, view-sights are provided to guide the engine-driver as to line, one connected on front of the engine and one fixed just in front of the driver, both sights to be parallel with the center line of engine. One workman stands on a platform fixed at the top of the apparatus (a portion of which is shown at s on Fig. 2) to operate the regulating-handles. At the front of the apparatus is the scratching-tool n cutting about an inch deep to roughly separate the parts to be cleaned by the respective shears m and n. For sides with upright borders the shear n cleans ofi the thinner portion to eight inches or thereabout distant from the border, while the cutting-wheel 7c pares off to the distance required. m, the shear behind the cutting wheel 70, cuts away the portion next the border. The shield r prevents the escape of loosened materials, guiding them in front of the raking-shear 0, which shear cleans off any inequality or vegetation beyond the ranges of the shears m and n and pushes all loosened materials to near the edge of road, where it is ready to be thrown off or carted away. The

shears are fixed on the frame so as to slightly overlap each other and at such heights as leaves the side road with a fall toward the edge or ditch, as the case may be. For sides opposite ditches the projecting shear m slightly overlapping the ditches, cuts away irregularities and vegetation on the surface beyond the reach of the shear m.
